New CDC COVID guidelines create controversy

Update: FDA warns at-home COVID tests can give false negatives.

In the medical community. No shit Sherlock. The guidelines recommend that "those who test positive for COVID-19 should stay home for at least five days, a period the CDC says people are most infectious. The CDC recommends those who test positive 'wear a high-quality mask when you must be around others at home and in public.'" But if you're exposed and test negative (on those inaccurate home tests)* then no need to quarantine.

I'm with the medical critics:

"Dr. Saskia Popescu took issue with the CDC removing the quarantine recommendation for those who have been exposed, particularly those unvaccinated. She also questioned the feasibility of people wearing masks in small offices where they will have to take them off for eating and drinking. Additionally, Popescu said discouraging routine testing ignores the 'high levels of asymptomatic cases. We should be providing people the resources to stay home if they're exposed, especially if unvaccinated and [without] vaccine-induced protection, not doing away with the quarantine guidance [altogether].'" 

"Dr. Judy Stone called the CDC's guidelines 'capitulation' in a tweet. 'What would be welcome to me and many others would be masking until rates are down and a focus on improving ventilation.  Immunocompromised/elderly people have been devalued and discarded.'"

* Per this infectious diseases physician: 

"Antigen tests are still fairly accurate, particularly when someone is experiencing symptoms and their viral load is very high. However, they can be less accurate when someone has a lower viral load, such as in someone without symptoms or someone very early in the course of their infection. This could lead to false negative test results. You could have a false negative result if, for example, you test yourself too soon after you’ve been exposed to someone with COVID-19, or if you test when you have no symptoms."
